Creped multi-ply tissue product
Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable, smooth and with low levels of Slough. In certain instances the creped tissue product have a geometric mean tensile (GMT) from about 700 to about 1,500 g/3″, a basis weight from about 45 to about 60 gsm and a Slough less than about 2.00 mg, more preferably less than about 1.50 mg, such as from about 0.10 to about 2.00, such as from about 0.25 to about 1.50 mg. The inventive tissue products also have good durability, such as a Durability Index from about 10.0 to about 20.0, smooth surfaces, such as a TS750 value from about 15.0 to 40.0 and low stiffness, such as a Stiffness Index less than about 10.0.
SOFT THROUGH-AIR DRIED FACIAL TISSUE
Disclosed am multi-ply tissue products, particularly creped and through-air dried facial tissue products, having improved strength and softness. For example, the products have a geometric mean tensile strength (GMT) greater than about 1,2000 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 g.Math.cm/cm.sup.2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 15.0. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.

SOFT WET PRESSED FACIAL TISSUE
Disclosed are multi-ply tissue products, particularly wet pressed facial tissue products that have been recreped. For example, disclosed are tissue products prepared from wet pressed tissue webs that have been recreped using a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web. The tissue products have improved strength and softness, such as a geometric mean tensile strength (GMT) greater than about 1,400 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 gocm/cm2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 20.0.
Dispersible adhesively bonded tissue laminate
Disclosed is a dispersible adhesively bonded wet tissue laminate and more particularly a dispersible wet wipe comprising two or more adhesively bonded tissue plies. Generally, the wipe comprises first, and second tissue plies adhesively bonded to one another by an adhesive, particularly a triggerable binder, disposed at the interface of the plies. The first and second tissue plies preferably comprise fibrous tissue plies and more preferably wet-laid tissue plies consisting essentially of conventional papermaking fibers. The adhesively bonded laminates are generally strong enough to withstand use, such as having a geometric mean wet tensile strength (GMWT) greater than about 250 g/in, but disperse quickly in water, such as having a Slosh Time less than about 60 minutes.

Paper wraps, paper wrapped products, and methods of making the same
The present disclosure provides paper wraps, paper wrapped products, such as rolled bath tissue, paper towel products, or bundles of rolled bath tissue or paper towels, and methods for covering a product or bundled products in a paper wrap. For example, printed paper wraps and their use are described, wherein the printed paper wraps comprise at least one heat-sealable adhesive that may be applied in varying locations, coverage levels, and patterns comprising different seal strengths, which may be sealed using heat and/or pressure external to the products for packaging and protective purposes.

Method and Apparatus for Folding and Opening-Up Wipes
Apparatus is provided for manufacturing a wipe in a three dimensional form out of an essentially flat piece of material. The apparatus produces a blank (12) of essentially flat planar form with a pleat folded on each side. The folded blanks are fed by a conveyor belt (21) to an opening station (22). The opening station comprises a pair of movable pinch rollers (34, 35) which selectively grab individual blanks from the conveyor belt and feed them via belts (32, 33) to a pair of counter-rotating drums (30, 31). The blanks are ejected from the drums, which partially opens them up in the process. The partially open blanks are fed onto a shaped former (37), where the final process of forming the wipe into its chosen three dimensional form is completed.
